    These images show the measured "Kd" value (diffuse attenuation coefficient). Studies have shown that this is a good analog to represent light attenuation and water clarity. This is a calculated value based on the amount of 490nm blue light as seen from space. These are 3 different satellites that pass over daily. The relevant data range is based on what has been determined to be relevant based on in situ diver reports.

  • Volusia MUR Overnight SST Composite (Summer)

    This satellite data product is updated daily around noon local time but includes SST data from 2 nights ago. So it is not as recent as other images. It's a composite of satellite images from several satellites creating a cloud free image. This unfortunately means edges are not as sharp and recent anomalies may not show up like it would on other products.
